Storm winger Suliasi Vunivalu.

Star Melbourne Storm winger Suliasi Vunivalu will leave the club at the end of the 2020 season to join rugby union team the Queensland Reds.

The Fijian international has scored 72 tries in 94 NRL games for the Storm and was the equal top try-scorer in the league in 2016 and 2017.

"The Storm has been wonderful to me, and I'm continuing to make great memories here," Vunivalu said.

"However, the offer from rugby union was too good for me to refuse, especially considering I have a young family who I want to do the best for.

"I was a rugby union player before switching to league and always thought going back to rugby was an option for my career and I never wanted to play for another NRL club.

"I'd hate to have to go up against Storm and my mates.

"Now this decision is public, I'm concentrating 100% on my final year in Melbourne and looking forward to doing the best I can for the boys, the coaches and all our members and fans."

Storm CEO Dave Donaghy said he didn't expect Vunivalu's performances to drop in the final year of his deal.

"We have had experience in the past with players signing deals for the future but remaining with Storm to see out their current contracts," Donaghy said.

"Players such as Cooper Cronk, Tohu Harris and Marika Koroibete come to mind.

"And in all of those cases, those players have excelled in their final year."
